The "godless congregation" doesn't need a 'church' for sundays they already find buildings to serve Satan and do their sinful thing on that day everywhere. Worldliness exists outside the church in every city and town on the earth where people sit daily in complete ignorance of the truth, spiritually dead and sauntering to hell and damnation. Then there is the religious atheism found 'IN' the church otherwise known as Liberalism or false witness. They amount to just as godless a congregating as do the reprobate atheists.
The simple fact is that God did not elect them to truth and reality.
4 Their idols are silver and gold, the work of men's hands. 5 They have mouths, but they speak not: eyes have they, but they see not: 6 They have ears, but they hear not: noses have they, but they smell not: 7 They have hands, but they handle not: feet have they, but they walk not: neither speak they through their throat. 8 They that make them are like unto them; so is every one that trusteth in them. Psalm 115.
